Abstract
The utility model discloses a structure of loosing core in efficient is two -way, including main slider, first side slide, second side slide, the front end of main slider be the partly of die cavity, its rear end is equipped with oblique guide pillar hole, its both sides limit is respectively being equipped with the draw runner to the inclined plane of internal contraction on two sides, the front end of first side slide and second side slide all be the partly of die cavity, the medial surface of first side slide and second side slide all is equipped with the spout, the spout of first side slide and the spout of second side slide slip respectively on the draw runner of main slider both sides. Because the utility model discloses a both sides limit of main slider is for respectively to the inclined plane of internal contraction and be equipped with the draw runner, and the spout of first side slide and the spout of second side slide slip respectively on the draw runner of main slider both sides, and when main slider was outwards taken out, first side slide and second side slide can be drawn close each other, and broke away from the back -off of product, and the structure is comparatively simple.
Description
Technical field
This utility model relates to a kind of injection mold, particularly relates to a kind of efficient two-way inner core pulling structure.
Background technology
Plastics injection mould is the instrument producing plastic, and application is widely.Indent that some products have relatively and set or back-off, need to carry out simultaneously inside and outside loose core.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, can extract the indent set or the efficient two-way inner core pulling structure of back-off relatively simultaneously.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of efficient two-way inner core pulling structure, including master slider, the first side slide, the second side slide；The front end of described master slider is a part for die cavity, and its rear end is provided with slanting guide pillar hole, and its dual-side is the inclined-plane shunk respectively inwards, is provided with draw runner on two sides；The first described side slide and the front end of the second side slide are all a part for die cavity, and the medial surface of the first side slide and the second side slide is all provided with chute, and the chute of the first side slide and the chute of the second side slide slip respectively on the draw runner of master slider both sides.
After using such scheme, owing to this utility model includes master slider, the first side slide, the second side slide；The dual-side of master slider is the inclined-plane shunk respectively inwards and is provided with draw runner, the chute of the first side slide and the chute of the second side slide slip respectively on the draw runner of master slider both sides, when master slider is outwards extracted out, first side slide and the second side slide can mutually be drawn close, and departing from the back-off of product, structure is relatively simple.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is sectional view of the present utility model；
Fig. 4 is matched moulds state diagram of the present utility model；
Fig. 5 is die opening state figure of the present utility model.
Detailed description of the invention
As Figure 1-Figure 5, this utility model is a kind of efficient two-way inner core pulling structure, including master slider the 1, first side slide the 2, second side slide 3.
The part that front end is die cavity of described master slider 1, its rear end is provided with slanting guide pillar hole 11, and its dual-side is the inclined-plane shunk respectively inwards, is provided with draw runner 12 on two sides.
The first described side slide 2 and the front end of the second side slide 3 are all a part for die cavity, the medial surface of the first side slide 2 and the second side slide 3 is all provided with chute 21,31, and the chute of the first side slide 2 and the chute 21,31 of the second side slide 3 slip respectively on the draw runner 12 of master slider 1 both sides.Master slider 1 simultaneously works as driving another first side slide 2 and the second side slide 3 to lock and the effect of loosing core, it is adaptable to small distance is loosed core.
Operation principle of the present utility model:
Master slider 1 is loosed core outward, and the first side slide 2 and the second side slide 3, simultaneously to contract, make the cavity portion of the first side slide 2 and the second side slide 3 front end depart from the back-off of product 10, product depanning.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
